We consider sample-size determination problem motivated by comparative clinical trials where patient outcomes are characterized by a bivariate outcome of efficacy and safety. Thall and Cheng (1999) presented a sample size methodology for the case of bivariate binary outcomes. We propose a bivariate Wilcoxon-Mann-Whitney(WMW) statistics for sample-size determination for binary outcomes, and this nonparametric method can be equally used to determine sample sizes of ordinal outcomes. The two methods of sample size determination rely on the same testing strategy for the target parameters but differs in the test statistics, an asymptotic bivariate normal statistic of the transformed proportions in Thall and Cheng (1999) and nonparametric bivariate WMW statistic in the other method. Sample sizes are calculated for the two experimental oncology trials, described in Thall and Cheng (1999), and for the first trial example the sample sizes of a bivariate WMW statistic are smaller than those of Thall and Cheng (1999), while for the second trial example the reverse is true.

Government Research Institutes(GRI), together with universities and private research labs, constitute the core of the Korea's national innovation system, The aim of this paper is to analyze the current system of GRIs and the National Research Councils(RC) in Korea, and suggest some policy recommendations conducive to achieving a world class competitive research system. To identify the problems and policy issues, we have conducted interviews (with executives staffs of RCs, GRIs and government ministries) and questionnaire surveys. For benchmarking purposes, we have visited 9 public research institutes in the USA, UK, Germany, and France. From the analysis of the problems revealed from the interviews and questionnaires, 6 policy variables are identified: three of them, which we call systemware variables, are governance structure, resources allocation system, and management control system; and the other three, which we call humanware variables, are visions and strategic goals, leadership, and research manpower, respectively. We have found that 1;he current GRI/RC systems are inefficient mainly due to the rigid and bureaucratic governance structure and inconsistent resource (i.e., government budgets) allocation systems. We reject the idea of replacing the current RC system with such radical alternatives as 're-governmentization'or 'privatization'. Instead we recommend that the government introduce a better system of governance and national budget allocations, which in turn would help induce a better management control systems, clear research visions and goals, strong leadership on the part of the RC chairman, and more creative and motivated researchers. These recommendations may provide opportunities and rooms for chairmen of RCs and presidents of GRIs to exercise more positive leadership in terms of fitting the visions and goal of GRIs to the national R&D strategy and creating a rational management control system as well as motivating researchers in GRIs to be more creative and productive.

The purpose of this study is to research the effects of English reading strategies on English reading comprehension by Korean college students. Reading strategy use was assessed through Oxford's self-report questionnaire in reading strategies. This study has three research questions. The first question was to investigate some reading strategies used by college students. The second question was to investigate the differences in reading strategies between two groups in gender. The third question was to investigate the differences in reading strategies of three college student groups according to their English proficiency estimated by reading scores. Some major findings of this study are as follows. First, college English learners use memory strategies most frequently of the six strategies, while using metacognitive strategies least frequently. Second, there exists a significant difference in reading strategies between the gender group. Third, there also exists a significant difference in reading strategies among the three groups divided according to English proficiency. This study shows that students' reading ability can be strengthened and motivated by some reading strategies in reading practice. It also means that it is necessary for English teachers to take into consideration the reading strategies suitable for the students in their reading classes.

The purpose of this study is to identify the posture correction program as the development of the posture maintenance performance, and search for the more efficient posture correction program. The data analysis was processed by SPSS. The data was analysed with $x^2$-test, t-test, pearson product moment correlation, and stepwise regression analysis. The finding of this study is as follows: There are the homogeneity between two groups was verified on the know ledges CF=.697, df=2, P>.05), self-efficacy(F=.098, df=2, P>.05) about the posture. The developed posture correction program has proved to enhance the posture maintenance performance(knowledge t=1.60, P<.05 ; posture manintenance t=7.69, P<.01). The type of posture correction program showed some significant differences (t=5.62, P<.01) in the accuracy of movement way among the factors of the posture maintenance performance. The posture maintenance performance affected self-efficacy. Therefore, the major conclusion is as follows: The posture correction program was meaningfully effective on developing the posture maintenance, and with practice created accuracy much more on the posture maintenance movement way. The development of the posture maintenance performance affected the increase of self-efficacy about the posture. The self-efficacy has proved so powerful factor to influence on the posture maintenance performance development. So, the posture correction program should be done systematically and continually, and developing the posture maintenance performance should be done with practice. After the education, it should be reinforced through practice, midterm identification and reeducation and motivated with recognizing the accurate posture measurement. And it should be created the correction program to develop the high self-efficacy about the posture. It needs the strategy to educate the correct posture individually, and to spread to the society for healthy life style.

In the past, management had been done over nurses rather than nursing and this brought the existence of general manager and as a result, nurse-manager's position and role are being threatend. For the up-bringing of nursing to firm professional recognition in the 21st century, it is firmly believed that nursing managers are to be in the position to play the role of general manager with professional qualifications; personal qualities and exact understandings on the role and function of each tier group under her/his management. 124 top(3 nursing superintendents), middle-range(23 supervisors) and unit managers(98 head-nurses) from 3 university hospitals in Seoul were interviewed in order to investigate their belief in the role, professional qualifications, personal qualities as well as the strategy for the development of their leadership qualities. The frame of reference for the interview were developed by the researcher in reference to relevant literatures. It was the common belief that qualifications o[ top-managers and mid-managers require an educational background of master's preparation or higher and clinical career for at least 15 years for top-managers and 5 -10 years for mid-managers. The personal qualities required by nurse managers include; leadership, initiative, judgement, self-confidence, flexibility, open-mindedness and strong motivation. Achievment-orientedness would greatly help them become excellent managers. On the other hand, [or more effective management, managers of each teir group are to fully understand their role and perform "their job responsibilities ie. Top managers are supposed to study with emphasis on organization, function and conceptual s~ill while mid-managers concentrate their effort on the development of skills for direction, guidance and human relationship. Unit managers also supposed to have abilities to manage their function with emphasis on development of clinical performance skill, for direction on operative aspects. The strategies for the development of leadership qualities include program-planning at individual instutional level as well as local, national and international level. Nurse-managers are to be motivated and encouraged to participate in the programs in order to effectively communicate within tier groups.oups.

As we increase installing computers, traditional commerce by paper document is replaced by Electronic Commerce, paperless document commerce. Electronic Commerce proves to be an intermediary for increasing efficiency on work, which makes us use it more. This study aims to contribute to streamline local export by analyzing trade firms and manufacturers' using status of Electronic Commerce on work in Pusan. I sent questionnaires to 202 firms working on trade in Pusan to do survey. The sample of this study consists of 96 of them. I analyze using status of Electronic Commerce on work based on those data. The result shows that the more the firms install facility to be able for Electronic Commerce and the better they understand Electronic Commerce related laws, the more they select that on work. Generally The firms in Pusan rarely select Electronic Commerce on work and even acknowledges how much that is needed on work. Considering all of them, this study shows the method of streamlining local export by Electronic Commerce as follows; First, all kinds of Electronic Commerce such as trade related site in Internet should be systemized. Second, the laws on Electronic Commerce should be established in details. Third, workers on firms should be educated on Electronic Commerce. Forth, the firms should install the facility for Electronic Commerce, assist financially and make marketing strategy for selecting Electronic Commerce on each step in work. In conclusion, export in Pusan would be streamlined when the use of Electronic Commerce, effective intermediary, is motivated and we take that method to use on work properly.
